Answer:

<h2>The ball has kinetic energy.</h2><h2>Kinetic energy is 945 J</h2>

Explanation:

Kinetic energy = 0.5 x Mass x Velocity²

Here the ball has mass and velocity.

So the ball has kinetic energy.

Kinetic energy = 0.5 x Mass x Velocity²

Mass = 2.1 kg

Velocity = 30 m/s

Kinetic energy = 0.5 x 2.1 x 30²

Kinetic energy is 945 J

A projectile is fired from the ground at a velocity of 30.0 m/s, 35.0 º from the horizontal. What is the maximum height the proj
Norma-Jean [14]

Answer:

Vy = V sin theta = 30 * ,574 = 17.2 m/s

t1 = 17.2 / 9.8 = 1.76 sec to reach max height

Max height = 17.2 * 1.76 - 1/2 * 4.9 * 1.76^2 = 15.1 m

H = V t - 1/2 g t^2 = 1.2 * 9.8 * 1.76^2 = 15.1 m

Time to fall from zero speed to ground = rise time = 1.76 sec

Vx = V cos 35 = 24.6 m / sec     horizontal speed

Time in air = 1.76 * 2 = 3.52 sec before returning to ground

S = 24.6 * 3.52 = 86.6 m
